Thompson Square's days as a duo are numbered. On Monday (Jan. 13), Shawna Thompson posted two photo on Instagram, showing off her bulging baby bump. The singer admits she's ready — but not quite ready — to become a mom.

"38 weeks and two days as of today," she writes, also revealing Baby Thompson's name. "Little Cooper will be here before we know it! #crazy #readybutnotready"

This will be Shawna and Keifer Thompson's first child together. The country duo announced that they were expecting in August with a photo drinking from Coke cans that read "Mom" and "Dad."

In September, they revealed the sex of the baby in a video, which showed the couple releasing a handful of blue and pink balloons as one remained that read, "It's a Boy!"

The pair have been married for 16 years — they met while both pursuing separate artist careers. They later joined forces as Thompson Square and saw success with their Grammy-nominated single "Are You Gonna Kiss Me or Not." The duo's latest single, the edgy "Trans Am," was released last year.

In an interview with Billboard, Keifer revealed the band's new sound. "It's been a little while since we had a single," he said. "We've just been writing our guts out and trying to prepare for the next chapter of Thompson Square and what we want to do next. 'Trans Am' is going to be the first page in that chapter. The whole album is going to be pretty aggressive and very rockin.' Hopefully, it won't sound like anything you hear on the radio."
